Smoked Salmon, Spinach, and Caper Pot Pie

Why I Love This Recipe
I smoked a very large salmon on my grill a few months ago and needed a way to use it up before I turned into a giant freezer-burn mess. I love the combination of capers and salmon, and wasn't sure if the spinach would work (yet another strong flavor0 but it turned out wonderful.
Ingredients You'll Need
Smoked Salmon (up to 1 cup, very finely shredded)
Bechamel Sauce (about 1 cup, make the sauce thick.)
Spinach (1 cup steamed or 1 freezer-block style package, thawed, drained)
Capers (3 tablespoons plus liquid, or more)
Small Russet Potato (boiled in salted water, 1/2 inch cubes)
1 Shallot
Dough for 1 Pie Crust (top only)
Egg Wash (1 egg mixed with 1 Tablespoon Water)
Salt & Pepper
Directions
Preheat oven to 350 F
While cooking potato, make Bechamel Sauce (look for a basic white sauce or Bechamel recipe to make 1 cup). Add thawed drained spinach to the Bechamel sauce, stir in minced shallot to warm. When potatoes are cooked, drain and cut into 1/2 cubes. Add cubed potatoes to Bechamel sauce.
Prepare 1 pie crust (keep in fridge until ready to use--after rolling it out, place it on plastic wrap and return to fridge.)
Use cooking spray to coat the bottom of pie pan. Fold in the shredded Smoked Salmon, Capers, and some of the liquid from the Caper jar into Bechamel. Sprinkle with salt to taste unless Bechamel recipe included salt. Sprinkle generously with freshly ground black pepper -- stir gently at this point.
Fold Bechamel into pie pan. Cover with top crust. Decorate with extra pieces of dough cut into fish shapes if desired. Poke with a few holes. Brush with Egg Wash.
Bake at 350 for about 20 to 30 minutes (until crust is golden brown and filing is bubbling.) Remove and let stand for at least 10 minutes before cutting.
